What are the four general categories of chemical agents?

Nerve agents, blister agents, blood agents, and choking agents. Riot control agents and incapacitating agents are also encountered but are not casualty agents in the same sense.

What are the levels of decontamination?

Immediate, operational, and thorough. Immediate decontamination is what the Soldier does right away to save life and limit spread. Operational decontamination lets the unit keep fighting by cleaning what Soldiers touch. Thorough decontamination reduces contamination enough to return to near-normal operations and requires support and a site.

What does MOPP stand for, and what are the postures?

Mission-oriented protective posture. The postures are MOPP Ready, MOPP 0, MOPP 1, MOPP 2, MOPP 3, and MOPP 4. The commander sets the level to balance protection against the heat and performance cost of wearing the gear.

What is M8 paper used for and what do the colors mean?

M8 paper detects and gives a presumptive identification of liquid chemical agents. Yellow or gold indicates a G-series nerve agent, dark green indicates a V-series nerve agent, and red indicates a blister agent. It only works on liquid, not vapor, and a color change is presumptive, not confirmation.

What is M9 paper and how does it differ from M8 paper?

M9 paper is adhesive-backed tape worn on the uniform or attached to equipment. It turns red, pink, or reddish purple when it touches a liquid chemical agent droplet. Unlike M8 paper, it detects that an agent is present but does not identify which agent it is.

What is required at MOPP Ready and at MOPP 0?

What is worn at MOPP 1, MOPP 2, MOPP 3, and MOPP 4?

The mnemonic SLUDGEM covers them: salivation, lacrimation or tearing, urination, defecation, gastrointestinal distress, emesis or vomiting, and miosis, which is pinpointing of the pupils. Add muscle twitching, difficulty breathing, and convulsions as exposure worsens.

Which MEDEVAC lines change between wartime and peacetime, and how?

Lines 6 and 9. In wartime, line 6 is the security of the pickup site and line 9 is CBRN contamination. In peacetime, line 6 is the number and type of wound, injury, or illness, and line 9 is a description of the terrain at the pickup site.
